    If you want help, you'll have to create an SSCCE that demonstrates exactly what you're talking about. Don't forget the code tags.

    Also, I might suggest using a better title- all caps and no mention of the actual problem will actually decrease your chances of getting help.

    Much more readable this way
    EDIT: You have weird spacing.... are you using an IDE or just notepad? I used my IDE to indent it.

    What exactly is your problem? Have you already attempted using println's to find out what the code is actually doing (compared to what it should be). Specific questions get specific answers

    Why do you have two classes for reading from the console? If one class reads and buffers the input, the other class will not know about it.

    iname[x]!=""
    You should use the equals method to compare Strings or use the length or is empty method.
